This allows for the replacement of only the liquid storage component or reuse of the refilled component when the liquid matrix is ​​depleted. However, this ultrasonic atomizing device suffers from the problem of excessive or excessively rapid transfer of liquid matrix to the ultrasonic atomizing core during the liquid delivery path, leading to phenomena such as oil splattering and liquid matrix leakage.

[0057] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application.

[0058] As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0059] As used here, when an element is described as being "fixed to" another element, it can be directly on the other element or there can be one or more intervening elements therebetween. When an element is described as being "connected to" another element, it can be directly connected to the other element or there can be one or more intervening elements therebetween.

[0060] As used here, the terms “up,” “down,” “left,” “right,” “inner,” “outer,” and similar expressions are used for illustrative purposes only.

[0061] As used herein, the terms “first,” “second,” etc., are used to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, particular order, or primary or secondary relationship of the indicated technical features.

[0062] like Figures 1-6 As shown, the ultrasonic atomizing device 10 provided in this application embodiment includes a liquid storage component 100, an ultrasonic atomizing component 200, and a power supply component 300.

[0063] In one example, the liquid reservoir 100 is detachably connected to the ultrasonic atomizing assembly 200, for example, by snap-fit ​​or magnetic connection, i.e., the connection is maintained by snap-fit ​​or magnetic adsorption.

[0064] In one example, the ultrasonic atomizing component 200 and the power supply component 300 are detachably connected, for example, by a snap-fit ​​connection or a magnetic connection. In another example, it is also feasible for the ultrasonic atomizing component 200 and the power supply component 300 to be non-detachable after being connected; the connection method is not limited.

[0065] Before use, the liquid reservoir 100, ultrasonic atomizing component 200, and power supply component 300 can all be packaged independently. In use, first connect the ultrasonic atomizing component 200 to the power supply component 300, then connect the liquid reservoir 100 to the ultrasonic atomizing component 200. Once the liquid matrix in the liquid reservoir 100 is depleted, the liquid reservoir 100 can be detached from the ultrasonic atomizing component 200 and replaced with a new one.

[0066] like Figures 8-9 As shown, the liquid storage assembly 100 includes a housing 101, a bottom cover 102, and a seal 103. The housing 101 and the bottom cover 102 are detachably connected, for example, by a snap-fit ​​connection. The seal 103 is disposed inside the housing 101 and is made of a flexible material, such as silicone.

[0067] A nozzle is provided at the top of the housing 101. The nozzle can be integrally formed with the housing 101 or formed separately. The nozzle can be held by the user to inhale the aerosol produced by atomization.

[0068] A reservoir 101a for storing a liquid matrix is ​​formed within the housing 101. The liquid matrix can be a liquid containing tobacco-containing substances, including volatile tobacco aroma components, or a liquid containing non-tobacco substances. For example, the liquid matrix may include water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruit flavoring components. Flavorings may include ingredients capable of providing the user with a variety of aromas or flavors. Vitamin mixtures may be substances containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. Additionally, the liquid matrix may include aerosol forming agents such as glycerin and propylene glycol.

[0069] The housing 101 also includes a delivery tube 101b communicating with the mouthpiece. The delivery tube 101b is used to transport aerosol to the mouthpiece for inhalation by the user. In a preferred embodiment, the delivery tube 101b is integrally formed with the housing 101, and the lower end of the delivery tube 101b is held on the bottom cover 102. Specifically, the bottom cover 102 is provided with a through hole 102a, and the lower end of the delivery tube 101b is inserted into the through hole 102a, so that external gas from the liquid storage component 100 can flow into the delivery tube 101b, be transported through the delivery tube 101b, and flow out from the mouthpiece.

[0070] The seal 103 has a through hole 103a, through which the lower end of the delivery pipe 101b can pass and be inserted into the through hole 102a; thus, a portion of the seal 103 can be sandwiched between the delivery pipe 101b and the bottom cover 102, thereby sealing the gap between the delivery pipe 101b and the bottom cover 102. Figure 8 It can also be seen that a portion of the seal 103 is sandwiched between the housing 101 and the bottom cover 102, and this portion of the seal 103 can seal the gap between the housing 101 and the bottom cover 102. With the above structure, the seal 103 can seal the liquid storage chamber 101a and prevent leakage of the liquid matrix.

[0071] In a further implementation, the bottom cover 102 is provided with protrusions 102b and 102c, both of which have through holes; the sealing element 103 is provided with through holes 103b and 103c, the through holes on protrusions 102b and 103b are aligned and connected, and the through holes on protrusions 102c and 103c are aligned and connected. The through holes on protrusions 102b and 103b form a first liquid outlet channel, one end of which is connected to the liquid storage chamber 101a, and the other end is connected to the outside of the liquid storage assembly 100; the through holes on protrusions 102c and 103c form a second liquid outlet channel, one end of which is connected to the liquid storage chamber 101a, and the other end is connected to the outside of the liquid storage assembly 100. Through the first and second liquid outlet channels described above, the liquid matrix stored in the liquid storage chamber 101a can flow out of the liquid storage component 100, for example, to the ultrasonic atomizing component 200.

[0072] In a further implementation, the first liquid outlet channel is provided with a puncturable or removable sealing element, such as a puncturable sealing membrane 102b1 disposed in the through hole of the protrusion 102b; the second liquid outlet channel is provided with a puncturable sealing element, such as a puncturable sealing membrane 102c1 disposed in the through hole of the protrusion 102c. Through the sealing membranes 102b1 and 102c1, the first and second liquid outlet channels can be blocked or sealed respectively before the liquid storage assembly 100 is connected to the ultrasonic atomizing assembly 200, preventing the liquid matrix from flowing out and allowing for independent packaging.

[0073] The bottom cover 102 is also provided with a snap-fit ​​hole 102d for snap-fit ​​connection between the liquid storage component 100 and the ultrasonic atomizing component 200, as detailed below.

[0074] like Figures 10-13 As shown, the ultrasonic atomizing assembly 200 includes a bracket 201, a seal 202, a seal 203, an ultrasonic atomizing core 204, a second liquid guiding element 205, and a first liquid guiding element 206.

[0075] The upper end of the bracket 201 is closed, and the lower end of the bracket 201 is open. The hollow part inside the bracket 201 communicates with the outside through the opening at its lower end.

[0076] The upper end of the bracket 201 is provided with a snap fastener 201a, which protrudes from the surface of the upper end of the bracket 201. When the liquid storage component 100 is connected to the ultrasonic atomizing component 200, the snap fastener 201a engages with the snap hole 102d, thereby realizing the snap connection between the liquid storage component 100 and the ultrasonic atomizing component 200.

[0077] The upper end of the support 201 is also provided with connectors 201b and 201c. Both connectors 201b and 201c protrude slightly from the surface of the upper end of the support 201. Both connectors 201b and 201c have through holes that communicate with the hollow part inside the support 201. The through hole of connector 201b forms a first liquid inlet channel, and the through hole of connector 201c forms a second liquid inlet channel. The ends of connectors 201b and 201c are both blade-shaped. When the liquid storage assembly 100 is connected to the ultrasonic atomizing assembly 200, the connector 201b can be inserted into the through hole of the protrusion 102b and puncture the sealing membrane 102b1, and the connector 201c can be inserted into the through hole of the protrusion 102c and puncture the sealing membrane 102c1. This allows the liquid matrix stored in the liquid storage chamber 101a to flow towards the hollow part inside the support 201 through the first liquid outlet channel and the through hole of the connector 201b, and to flow towards the hollow part inside the support 201 through the second liquid outlet channel and the through hole of the connector 201c.

[0078] It is understood that the sealing element is not limited to the sealing membrane scenario described above; in other examples, the sealing element may be a flexible sealing plug, such as silicone, which is at least partially filled in the liquid outlet channel and can be removed from the sealed position by being pushed open by the connector; in yet another example, the sealing element may be a combination of a spring and a movable sealing member, which can be removed from the sealed position by being pushed open by the connector, and the spring can drive the sealing member to reset and hold it in the sealed position.

[0079] The upper end of the bracket 201 also has a through hole 201d that communicates with the hollow part inside the bracket 201. The side wall of the bracket 201 is also provided with a snap fastener 201e and a snap hole 201f, as detailed below.

[0080] The seal 202 is disposed at the upper end of the bracket 201. The seal 202 may be made of a flexible material, such as silicone.

[0081] The seal 202 has a notch 202a corresponding to the snap fastener 201a, such that the snap fastener 201a can be inserted into the notch 202a and protrude from the seal 202.

[0082] The seal 202 has a sealing hole 202b corresponding to the connector 201b and a sealing hole 202c corresponding to the connector 201c. When the seal 202 is assembled onto the bracket 201, the protruding portion of the connector 201b or one end of the connector 201b inserted into the first liquid outlet channel is located in the sealing hole 202b, and the protruding portion of the connector 201c or one end of the connector 201c inserted into the second liquid outlet channel is located in the sealing hole 202c. Thus, when the liquid storage assembly 100 is connected to the ultrasonic atomizing assembly 200, the protrusion 102b can be inserted into the sealing hole 202b for sealing, and the protrusion 102c can be inserted into the sealing hole 202c for sealing. This allows the protrusions 102b and 102c to be sealed before the connector 201b punctures the sealing membrane 102b1 or the connector 201c punctures the sealing membrane 102c1, preventing leakage of the liquid matrix.

[0083] The seal 202 has a sealing hole 202d corresponding to the through hole 201d. When the seal 202 is assembled onto the bracket 201, the sealing hole 202d is aligned and connected to the through hole 201d, and the lower end of the sealing hole 202d can extend into the through hole 201d, thereby forming a seal. When the liquid storage assembly 100 is connected to the ultrasonic atomizing assembly 200, the lower end of the delivery pipe 101b abuts against the seal 202, and the delivery pipe 101b is aligned and connected to the sealing hole 202d.

[0084] The seal 203 may be made of a flexible material, such as silicone. The seal 203 is housed within the bracket 201. The shape of the seal 203 matches the shape of the bracket 201. The upper end of the seal 203 is closed, and the lower end of the seal 203 is open. The hollow portion inside the seal 203 communicates with the outside through the opening at its lower end.

[0085] The upper end of the seal 203 is recessed to form a receiving cavity 203a. The upper end of the seal 203 also has through holes 203b, 203c, and 203d communicating with the hollow portion inside the seal 203. Through holes 203b, 203c, and 203d are distributed along the radial direction of the seal 203, with through holes 203b and 203c located on either side of through hole 203d. A capillary groove 203d1 and an air inlet 203d2 are also provided on the sidewall of through hole 203d. The seal 203 also has an air guide tube 203e, as detailed below.

[0086] The ultrasonic atomizing core 204 is at least partially housed or mounted within the bracket 201, and is positioned near the lower end of the through-hole 203d. The ultrasonic atomizing core 204 is used to generate high-frequency oscillations to atomize the liquid matrix into an aerosol.

[0087] The second liquid guiding element 205 can be made of flexible strip or rod-shaped fibrous material, such as cotton fiber, non-woven fiber, or sponge. One end of the second liquid guiding element 205 passes through the through hole 203b and is bent and arranged on the bottom wall of the receiving cavity 203a. The other end of the second liquid guiding element 205 passes through the through hole 203c and is bent and arranged on the bottom wall of the receiving cavity 203a. A portion of the second liquid guiding element 205 remains in contact with the ultrasonic atomizing core 204, and this portion of the second liquid guiding element 205 is located between the two ends of the second liquid guiding element 205. The second liquid guiding element 205 extends approximately along the radial direction of the ultrasonic atomizing assembly 200.

[0088] The first liquid guiding element 206 is made of an elastic organic porous material, exhibiting moderate flexibility and rigidity. In implementation, the first liquid guiding element 206 has an elastic modulus or stiffness smaller than that of the material of the support 201 and larger than that of the material of the second liquid guiding element 205. The first liquid guiding element 206 is at least partially housed in the receiving cavity 203a, and the lower surface 206c (second surface) of the first liquid guiding element 206 maintains contact with a portion of the second liquid guiding element 205 disposed on the bottom wall of the receiving cavity 203a. The first liquid guiding element 206 has a through hole 206a corresponding to the through hole 203d.

[0089] After the seal 203, ultrasonic atomizing core 204, second liquid guiding element 205 and first liquid guiding element 206 are assembled to the bracket 201, the liquid matrix stored in the liquid storage chamber 101a can flow into the receiving chamber 203a of the seal 203 through the through hole of the first liquid outlet channel and connector 201b or through the through hole of the second liquid outlet channel and connector 201c. Specifically, the upper surface 206b (first surface) of the first liquid guiding element 206 covers the through holes of the connector 201b and the connector 201c. The liquid matrix stored in the liquid storage chamber 101a can flow into the upper surface 206b of the first liquid guiding element 206 through the first liquid outlet channel and the through hole of the connector 201b or through the second liquid outlet channel and the through hole of the connector 201c, thereby being absorbed and stored by the first liquid guiding element 206. Since the lower surface 206c of the first liquid guiding element 206 is in contact with a portion of the second liquid guiding element 205 arranged on the bottom wall of the receiving cavity 203a, the first liquid guiding element 206 can also transfer the liquid matrix to the contacting second liquid guiding element 205. In this way, the second liquid guiding element 205 can absorb the liquid matrix in the first liquid guiding element 206 and transfer it to the ultrasonic atomizing core 204 through capillary wetting, so that the ultrasonic atomizing core 204 can atomize the liquid matrix transferred by the second liquid guiding element 205 into an aerosol. By drawing liquid matrix from the first liquid matrix element 206 through the second liquid guiding element 205, phenomena such as oil splattering can be avoided, which are caused by excessive or rapid transfer of liquid matrix to the ultrasonic atomizing core 204.

[0090] After the sealing element 203, ultrasonic atomizing core 204, second liquid guiding element 205, and first liquid guiding element 206 are assembled into the bracket 201, the lower end of the through hole 201d passes through the through hole 206a of the first liquid guiding element 206 and aligns with the through hole 203d. The upper end of the through hole 203d can extend into the through hole 201d, thereby forming a seal; the lower end of the through hole 203d abuts against the second liquid guiding element 205, thereby keeping part of the second liquid guiding element 205 in contact with the ultrasonic atomizing core 204. In the above structure, the through hole 203d, the through hole 201d, and the sealing hole 202d together constitute a delivery channel. Air in the bracket 201 can flow into the through hole 203d from the air inlet 203d2, and then flow into the delivery pipe 101b (as shown by R2 in the figure) after passing through the through hole 201d and the sealing hole 202d in sequence.

[0091] In the above configuration, the seal 203 abuts against at least a portion of the second liquid guiding element 205, thereby pressing at least a portion of the second liquid guiding element 205 against the lower surface 206c of the first liquid guiding element 206.

[0092] In the above structure, since the lower end of the through hole 203d abuts against the second liquid guiding element 205, and a portion of the second liquid guiding element 205 remains in contact with the ultrasonic atomizing core 204, and the capillary groove 203d1 on the sidewall of the through hole 203d has one end connected to the receiving cavity 203a and the other end extending to the lower end of the through hole 203d, the liquid matrix in the receiving cavity 203a can also be guided to the second liquid guiding element 205 through the capillary groove 203d1, thereby guiding it to the ultrasonic atomizing core 204.

[0093] In a further implementation, the air inside the support 201 can flow toward the receiving cavity 203a through the air guide tube 203e, and flow into the through hole of the connector 201b along the gap between the second liquid guiding element 205 and the seal 203, the gap between the first liquid guiding element 206 and the seal 203, and the gap between the first liquid guiding element 206 and the support 201 (in other examples, it can flow along the gap between the second liquid guiding element 205 and the seal 203, and the gap between the first liquid guiding element 206 and the seal 203, but not along the gap between the first liquid guiding element 206 and the support 201), thereby flowing toward the liquid storage cavity 101a through the first liquid outlet channel. In this way, air can be supplied to the liquid storage chamber 101a to balance the air pressure in the liquid storage chamber 101a and the support 201, that is, to balance the air pressure in the liquid storage chamber 101a and the external air. This ensures that the liquid matrix stored in the liquid storage chamber 101a can flow smoothly to the first liquid guiding element 206 through the through hole of the first liquid outlet channel and the connector 201b or through the through hole of the second liquid outlet channel and the connector 201c. In the above structure, the gap between the second liquid guiding element 205 and the seal 203, the gap between the first liquid guiding element 206 and the seal 203, and the gap between the first liquid guiding element 206 and the support 201 constitute a ventilation channel. The air guide tube 203e is connected to the ventilation channel and extends toward the ultrasonic atomizing core 204. As can be seen from the above, the ventilation channel is not connected to the through hole of the connector 201c, or the ventilation channel avoids or is far away from the through hole of the connector 201c.

[0094] like Figures 14-15 As shown, the power supply assembly 300 includes a housing 301, a frame 302, a circuit board 303, and a battery cell 304.

[0095] The housing 301 is generally cylindrical. The upper end of the housing 301 is open, and the lower end is closed. The frame 302, the circuit board 303, and the battery cell 304 are all housed inside the housing 301. A snap-fit ​​groove 301a is provided on the inner surface of the housing 301, and an air inlet 301b is also provided on the side wall of the housing 301.

[0096] The frame 302 has a receiving cavity 302a with an opening near the upper end of the housing 301. The sidewall of the receiving cavity 302a is spaced apart from the inner surface of the housing 301. The sidewall of the receiving cavity 302a is provided with a snap fastener 302a1 and a flange 302a2. The flange 302a2 extends from the sidewall of the receiving cavity 302a toward the inner surface of the housing 301. In a preferred embodiment, the flange 302a2 abuts against the inner surface of the housing 301, thereby dividing the hollow part inside the housing 301 into upper and lower parts. The liquid storage assembly 100 and the ultrasonic atomizing assembly 200 are arranged in the upper mounting space (first mounting space), and the circuit board 303 and the battery cell 304 are arranged in the lower mounting space (second mounting space). The receiving cavity 302a is also provided with a protrusion 302a3, which is annular and surrounds the bottom wall of the receiving cavity 302a to form an open receiving cavity 302a4. Through holes 302a5 and 302a6 are also provided between the protrusion 302a3 and the side wall of the receiving cavity 302a.

[0097] The frame 302 also has an extension 302b extending from the bottom wall of the receiving cavity 302a toward the lower end of the housing 301. The extension 302b is provided with a receiving cavity 302b1, which is connected to the receiving cavity 302a through a through hole 302a6.

[0098] The circuit board 303 is electrically connected to the battery cell 304, and both the circuit board 303 and the battery cell 304 are held on the extension 302b.

[0099] The circuit board 303 can control the overall operation of the ultrasonic atomizing device 10. Specifically, the circuit board 303 controls not only the operation of the battery cell 304 and the ultrasonic atomizing assembly 200, but also the operation of other components in the ultrasonic atomizing device 10. Furthermore, the circuit board 303 can determine whether the ultrasonic atomizing device 10 is operable by checking the status of its components.

[0100] The circuit board 303 includes at least one control unit. The control unit may include a logic gate array, or may include a combination of a general-purpose microcontroller and memory for storing programs executable in the microcontroller. Furthermore, those skilled in the art will understand that the circuit board 303 may include another type of hardware.

[0101] An electrode 302a is provided on the circuit board 303. One end of the electrode 302a is connected to the circuit board 303, and the other end of the electrode 302a passes through a through hole (not shown) on the bottom wall of the receiving cavity 302a and is arranged in the receiving cavity 302a4.

[0102] The circuit board 303 also includes an airflow sensor 302b, such as a common microphone. The airflow sensor 302b is at least partially housed in a receiving cavity 302b1, and one of the sensing surfaces of the airflow sensor 302b communicates with the receiving cavity 302a through a through hole 302a6.

[0103] Battery cell 304 provides power for operating the ultrasonic atomizing device 10. For example, battery cell 304 can provide power to cause the ultrasonic atomizing core 204 to oscillate at a high frequency, and can provide the power required to operate the circuit board 303. In addition, battery cell 304 can provide the power required to operate other components provided in the ultrasonic atomizing device 10.

[0104] Cell 304 can be a rechargeable battery or a disposable battery. Cell 304 can be, but is not limited to, a lithium iron phosphate (LiFePO4) battery. For example, cell 304 can be a lithium cobalt oxide (LiCoO2) battery or a lithium titanate battery.

[0105] When the ultrasonic atomizing component 200 is connected to the power supply component 300, the snap fastener 201e engages with the snap fastener slot 301a to achieve a snap fastener connection between the ultrasonic atomizing component 200 and the power supply component 300.

[0106] When the ultrasonic atomizing component 200 is connected to the power supply component 300, the snap-fit ​​hole 201f and the snap-fit ​​buckle 302a1 cooperate to realize the snap-fit ​​connection between the ultrasonic atomizing component 200 and the frame 302.

[0107] When the ultrasonic atomizing component 200 is connected to the power supply component 300, the end face of the lower end of the bracket 201 abuts against the flange 302a2.

[0108] When the ultrasonic atomizing assembly 200 is connected to the power supply assembly 300, the open end of the receiving cavity 302a extends into the sealing member 203. A portion of the sealing member 203 is sandwiched between the side wall of the receiving cavity 302a and the inner surface of the support 201, with the end face of the open end of the receiving cavity 302a abutting against the inner surface of the sealing member 203. In this way, the sealing member 203 can seal the opening of the receiving cavity 302a, making the receiving cavity 302a a closed chamber.

[0109] When the ultrasonic atomizing assembly 200 is connected to the power supply assembly 300, the ultrasonic atomizing core 204 is at least partially housed in the receiving cavity 302a4, and the ultrasonic atomizing core 204 remains in contact with the other end of the electrode 302a, thereby forming an electrical connection.

[0110] Referring to the liquid guiding path R1 in the figure, the liquid matrix stored in the liquid storage chamber 101a can flow toward the receiving cavity 203a of the seal 203 through the through hole of the first liquid outlet channel and the connector 201b or through the through hole of the second liquid outlet channel and the connector 201c, and thus be absorbed by the first liquid guiding element 206; the second liquid guiding element 205 absorbs the liquid matrix in the first liquid guiding element 206 and transfers it to the ultrasonic atomizing core 204 through capillary wetting.

[0111] Referring to the airflow channel R2 in the figure, air outside the ultrasonic atomizing device 10 can flow into the housing 301 through the air inlet 301b, that is, into the lower part of the installation space inside the housing 301; then it flows into the receiving cavity 302a through the through hole 302a5 (the through hole 302a5 forms an air channel connecting the upper part of the installation space and the lower part of the installation space); the air in the receiving cavity 302a can flow into the through hole 203d from the air inlet 203d2, mix with the aerosol generated by the ultrasonic atomizing core 204, and then flow into the delivery pipe 101b after passing through the through hole 201d and the sealing hole 202d in sequence; finally, it flows out from the nozzle.

[0112] Since the sensing surface of the airflow sensor 302b is connected to the receiving cavity 302a through the through hole 302a6, the airflow sensor 302b can sense changes in the airflow in the airflow channel, thereby generating a corresponding electrical signal. Based on this electrical signal, the control unit of the circuit board 303 can control the operation of the ultrasonic atomizing core 204, for example, control the ultrasonic atomizing core 204 to generate high-frequency oscillations, thereby atomizing the liquid matrix into an aerosol.

[0113] Referring to the ventilation path R3 in the figure, the air in the receiving cavity 302a can flow toward the receiving cavity 203a through the air guide tube 203e, and flow into the through hole of the connector 201b along the gap between the second liquid guiding element 205 and the seal 203, the gap between the first liquid guiding element 206 and the seal 203, and the gap between the first liquid guiding element 206 and the support 201 (in other examples, it can flow along the gap between the second liquid guiding element 205 and the seal 203, and the gap between the first liquid guiding element 206 and the seal 203, but not along the gap between the first liquid guiding element 206 and the support 201), thereby flowing toward the liquid storage cavity 101a through the first liquid outlet channel. In this way, air can be added to the liquid storage chamber 101a to balance the air pressure in the liquid storage chamber 101a and the support 201, that is, to balance the air pressure in the liquid storage chamber 101a and the external air, so as to ensure that the liquid matrix stored in the liquid storage chamber 101a can flow smoothly to the first liquid guiding element 206 through the through hole of the first liquid outlet channel and the connector 201b or through the through hole of the second liquid outlet channel and the connector 201c.

[0114] Figures 18-19This is another embodiment of the ultrasonic atomizing device 10 provided in this application, and... Figures 1-17 The examples are different:

[0115] exist Figures 18-19 In the example, a magnetic element 102d' is provided on the bottom cover 102, and a magnetic element 201a' is provided on the upper end of the bracket 201. When the liquid storage assembly 100 is connected to the ultrasonic atomizing assembly 200, the magnetic element 201a' cooperates with the magnetic element 102d' to achieve a magnetic connection between the liquid storage assembly 100 and the ultrasonic atomizing assembly 200.

[0116] exist Figures 18-19 In the example, connectors 201b and 201c are arranged at intervals along a radial direction of the ultrasonic atomizing assembly 200, that is, the first liquid inlet channel and the second liquid inlet channel are arranged at intervals along the first radial direction of the ultrasonic atomizing assembly 200; while the second liquid guiding element 205 extends along the second radial direction of the ultrasonic atomizing assembly 200, and the second radial direction is perpendicular to the first radial direction. This facilitates providing space for the arrangement of the ventilation channel.
